Brookhaven graphite reactor

Four cal. 30 percussion primers (the No 26 and No 72M production types and the X40 and X41 exptl types) were irradiated both by Co60 gamma rays in the Brookhaven graphite reactor and were then tested for impact sensitivity, A large increase in impact sensitivity occurred, usually followed at 10s R or 10lB nvt with a 107 R gamma component by a drastic decrease. Reactor-irradiated production primers showed a second sensitization trend. The No 72M primers were considerably more radiation resistant than the No 26 at high dose but considerably less at low dose. The compns used in the primers are listed in Table 6. 

First peacetime nuclear reactor Construction on the Brookhaven Graphite Research Reactor at Brookhaven Laboratory on Long Island, New York, is completed. 

At Brookhaven National Laboratory and at Kernforschungszentrum Karlsruhe, small computers performed data-handling chores on a timesharing basis. The Brookhaven system provided data collection and sorting functions for two independent neutron time-of-flight experiments 44). At the BNL Graphite Research Reactor in 1963, an SDS 910 computer with a 4096 24-bit memory, paper tape equipment, typewriter, and priority-interrupt system served as both a 1024 channel time analyzer for fast-neutron chopper total and partial cross-section experiments and a 256-channel time analyzer for slow-neutron chopper experiments.

The uranium-bismuth fuel system is flexible and can be u.sed in many designs. Although other types of liquid-metal systems are certainly possible, the LMFR at Brookhaven is being designed as a thermal reactor in which the fuel is di.ssolved or suspended in a liquid hea y-metal carrier. Ordinarily, the liquid metal is bismuth for highest neutron economy, but other systems such as lead or lead-bismuth eutectic may be used. The moderator is graphite, although beryllium oxide has also been considered.
